What device do you measure how bright something is?
Light or brightness is something that is measured subjectively, as it is directly based on the brightness seen by the human eye. Luxmeter is a brilliantly designed device that measures brightness and uses the unit lux. Lux is the SI unit of illuminance that measures luminous flux per unit area. Digital Luxmeters is equipped with a data logger or, in a simple term, an internal memory that records and saves the reading. Luxmeters are widely used in several applications these days to measure levels of light in critical places like schools, hospitals, production areas, laboratories, which play a key role in increasing the safety of these places.
